//		four properties of Objects (BITS)
//		1) itentity ( every object has a seperate identity, even if they are the same(== compares objects if they point to eachother, compared in the heap))
//		2) state ( properties given, usually fields and values of fields)
//		3) type (class name is usually type)
//		4) behavior (represented by methods)
//		
//		Can go in class:
//			Fields
//			Methods
//			Constructor(method declaration, named after class (capitalized) and no return type)
//			Initializerr (runs before any constructors)
//			Another Class!!!!
//			constructor chaining (constructors calling constructors)
//		
//		Parent classes (base class) passes (extends) inheritance ( behavior and states ) to it's subclasses
//				example : Subclass extends baseclass {    (tests are an example)   CTRL O to see outline 
//		all classes extend to Object class
